Definitions

  • the present invention relates to a day-night episcope allowing the driving of a tank comprising a shielding.
  • Tank day driving episcopes are usually made up of a rhombohedron prism crossing the shielding under which the station is steering.
  • the object axis of this optical system is horizontal and outside the shield and the image axis is also horizontal, but of course inside shielding, at the driver's eye level.
  • Field of these episcopes is limited by its section, i.e. by the dimensions of their positioning hole in the shield ( Figure 1).
  • Night driving episcopes feature usually a light intensifier tube and a lens whose axis is bent and which forms an image of the landscape on the photocathode of this intensifier tube of light, the screen of which is observed by means of a optical system whose axis is also bent and which is usually a binocular ( Figure 2).
  • intensifier sensor of matrix-light resulting from the association of a light intensifier tube and sensor reading matrix, for example CCD (Charge Coupled Device).
  • CCD Charge Coupled Device
  • a goal forms the image of the landscape on an intensifier tube light.
  • the intensified image provided by the screen of the tube is then formed on a matrix sensor.
  • the signals provided by this matrix can be transmitted remotely and observed on a display screen by an appropriate optical system, for example by a binocular, or even directly on a large screen cut.
  • a first type of day-night driving episcope integrates into the same mechanics, practically side by side, a day driving episcope and a driving at night. These episcopes avoid daily manipulations mentioned above, but are bulky since the dimensions of the positioning in the shield both limit the day periscope field and periscope field at night, and that the surface of the armor passage must so be almost double that needed to one episcope.
  • the document EP-A-428.955 describes a device for panoramic surveillance from a closed object, in particular a combat vehicle, comprising a device daytime panoramic view and a set of sensors mounted rotating in all directions and intended for shooting nocturnal. All night view sensors produced electrical signals transmitted by cable through the wall object or combat vehicle and provide a picture on a screen inside the object or combat vehicle.
  • the object of the invention is to propose an episcope of day-night driving for tank which allows, the day, the formation of a direct image of the landscape and ensures night vision, without requiring an increase in dimensions of the positioning hole of the episcope in the shielding, with equal fields, compared to an episcope single day.
  • the invention relates to an episcope day-night driving of a tank according to claim 1.
  • rhombohedron prism can be replaced by any equivalent optical system, without this does not change this type of constraint.
  • a night episcope 6 is composed a light intensifier tube 7 comprising a input side 8 and a screen 9.
  • An angled lens 10 form the image of the landscape in direction 11 on the input face 8 of the light intensifier tube, and a bent objective 12 produces the image intended for the observer 13.
  • This episcope crosses the shield 14 through hole 15, the dimensions of which condition those of his field.
  • the day-night episcope produced according to the invention and shown in Figure 3, has a prism rhombohedron passing through a hole 22 the shield 23 and allows driver 24 to observe the landscape in the direction 25.
  • a shooting module 26, outside the shield 23, includes a lens 27, a tube light intensifier 28, a sensor array reading 29 coupled to the image side 30 of the tube light intensifier by an optical system 31.
  • a display module 32 includes a screen display 33, connected to the shooting module 26 by the electric cable 34, and a bent lens 35, 36 infinitely rejecting the image formed by the screen of visualization 33 and allowing its observation by the conductor 24, from the same position as that allowing observation through the day episcope 21.
  • the electric cable 34 for connection between the module of shooting and the viewing module crosses the shield 23 through a passage 37.
  • This day-night episcope therefore allows the traditional day visualization and keeps it its comfort and its resistance and its field, and brings the possibility of good quality vision at night at from the same driver observation post.
  • the traditional day episcope equipping tanks old can be changed.
  • a shooting module 26 and a display module 32 being added thereto and requiring the drilling of the shield 23 only for ensure the passage of the electrical connection cable 34.
  • the shooting module 26 can be perfected, so that it incorporates other imaging systems capable of forming images convertible into electrical signals and that it is therefore possible to transmit by cable electric 34.
  • the socket module view 26 may include a thermal infrared camera and a day camera. Thermal infrared camera can be used day or night.
  • These different image acquisition devices included in the shooting module can be fitted with optical systems to improve their performance, such as multifocal lenses or at variable focal lengths, the rotation devices ....
  • the images formed by both can be overlapped by a blade semi-transparent 38, as shown in the Figure 4.
  • the overlay of these images can also be produced by means of a tilting mirror, this which allows observation without loss of luminous flux.
  • the image provided by the shooting module can be distributed to stations other than the conductor via a modular box intermediate, for example to the tank commander. These images can be subject to different treatments and can also be transmitted to outside, at other tanks or at the commandment.
